I don't want to see Superman moving planets until a later installment, like JL or MOS 2. Give him something to work towards. I much prefer they portray a strength level of somewhere between 100,000- 400,000 tons.

If he starts of as able to move planets in MOS, he won't need to sundip and amp up in later movies.
Seriously, they should gradually make him stronger every movie he can have an insane strength feat in JL.
